2023-2025 Cadillac LYRIQ Fender: Charge Port, Lighting, and Replacement Guide

Symptoms of a Damaged Fender

Because a fender is a body panel, failure is almost always the result of physical impact or corrosion. Symptoms are typically visual or related to the components it houses.

• Visible Damage: The most obvious symptom is visible damage from a collision, such as dents, deep scratches, or cracks in the paint. Even minor impacts can cause damage that may lead to rust over time.
• Poor Panel Gaps: Misalignment with the hood, front bumper, or driver/passenger door is a sign of a bent fender or improper installation. On the driver's side, this can cause the door to rub against the charge port panel.
• Charge Port Door Malfunction: On the driver's side, issues with the charge port door opening, closing, or aligning correctly can be caused by fender damage. Owners have reported the driver's door catching on the charge port door, sometimes bending the fender metal.
• Misaligned Lighting: If the vertical LED light strips do not align perfectly with the corresponding lights in the bumper or grille, it could indicate the fender has shifted or is damaged.
• Loose Trim or Moldings: The plastic wheel arch trim can become loose or detach, sometimes due to broken clips from the factory or during a previous repair.

Buying a Used 2023-2025 LYRIQ Fender

A used OEM fender is an excellent way to save money, especially compared to a new part from a dealer. Because these parts are designed by the manufacturer, they guarantee a perfect fit, which is critical on a vehicle with such tight tolerances. Aftermarket versions of this complex fender are not widely available, making used OEM the best alternative to new.

When inspecting a used fender, pay close attention to the following:

• Check for Hidden Repairs: Look at the back side of the fender for signs of body filler (often called Bondo), sanding marks, or non-factory welds. A magnet can help detect areas with thick filler. A professionally repaired panel is acceptable, but a poorly done job will fail over time.
• Inspect All Mounting Points: Carefully check every tab, bracket, and mounting hole. On the LYRIQ, the points where the fender meets the bumper, headlight, and A-pillar are critical for alignment. A broken tab can cause a poor fit that is impossible to correct.
• Examine the Charge Port Area (Driver's Side): Look for any warping, cracks, or stress marks around the charge port opening. Damage here can prevent the charge port door assembly from seating correctly.
• Verify It's a Bare Panel: Used fenders are almost always sold bare. This means you will need to transfer your original LED lighting, charge port mechanism, and any wiring harnesses. Ensure the used panel has the correct provisions for these parts.
• Note the Charge Port Mechanism Change: Early 2023 to mid-2025 LYRIQ models have a spring-loaded charge port door that can "boing" open. Late in the 2025 model year, GM introduced a new, smoother, slower motorized mechanism. This was a hardware change and cannot be retrofitted to an older vehicle. The fender panel itself is the same, but be aware of this difference in operation.

Known Issues, Recalls, and TSBs

Known Issues

• Driver's Door / Charge Port Interference: Several owners have reported the driver's door rubbing or catching on the charge port door or the surrounding fender panel. This is due to panel misalignment from the factory or following a repair. In some cases, it has caused paint damage and bent metal. This should be checked and adjusted by a professional body shop.
• Loose Fender Trim: There are reports of the plastic wheel arch trim becoming loose. This is often due to broken retaining clips, which may need to be replaced.
• Charge Port Door Mechanism: The abrupt opening of the charge port door on earlier models was a common complaint. While not a failure, it's a known characteristic. Models built after approximately July 2025 have an updated, smoother mechanism.

Recalls & Technical Service Bulletins (TSBs)

As of mid-2026, there are no specific recalls or TSBs for the fender panel itself. However, several vehicle-wide recalls and service campaigns are relevant for owners.

• NHTSA Campaign 25V232000: This recall addresses improperly tightened front stabilizer bar bracket bolts. If the bar detaches, it could damage high-voltage cables or coolant lines located in the wheel well area, behind the fender. This is important context for any collision repair in this area.
• Software Updates: Many TSBs for the LYRIQ involve software updates to improve everything from the infotainment system to charging performance. For example, TSB N232428540 is a comprehensive software update for 2023 models. While not related to the fender, ensuring the vehicle's software is up-to-date is a key part of overall maintenance.

Replacement & Installation

Replacing a LYRIQ fender is a complex job that should be left to a professional body shop with experience in modern EVs.

• Difficulty: 4.5 out of 5.
• Why it's difficult: The process involves disconnecting the 12V battery, carefully removing and transferring the LED lighting assembly and its control modules, and (on the driver's side) transferring the entire motorized charge port assembly. Achieving perfect panel gaps with the hood, bumper, and door is critical and requires skill.
• Painting Required: New and used fenders come unpainted or with the original paint. To achieve a perfect match, a body shop must paint the new fender and often "blend" the paint into the adjacent door and bumper to ensure it's visually seamless. You must verify your vehicle's paint code before any work begins.

Cost to Replace a 2023-2025 Cadillac LYRIQ Fender

Costs can vary significantly based on your location and the chosen parts. The primary cost driver is the labor for painting and installation.
